How would you use a laser? They typically have a very focused beam, and most likely you would need a photo detector or am I missing something?

And to think of it, there you can fart as much as you like, and not feel guilty about greenhouse gasses etc.
But there is no sound in space. Kinda takes the fun out of it...
Oh, I don't know about that. Do lighters work in space?

I think without pressure, the gas would just go poof like an elevator fart. Smell not included.![]()
That was my point about the collimated beam, in this case you have a small ball dropping down a very large diameter how would one make a laser detect over the whole cross sectional area of the diameter? With a laser as is you would only detect if the ball crossed the line of the laser so the ball may easily drop without hitting the laser line.
